Hi,

I had posted the same query a weeks ago but didnt get any reply.just adding more details and hoping som1 can help me.

Here is the real problem:

We have a client whose users uses cisco vpn clients to connect the Corporate LAN from public network and able to access as expected and also able to run netmeeting from his pc but when users trying to run netmeeting between two vpn clients connected from public network having same pool ip, it doesn't work.

Thanks & regards

Try removing "nat (outside) 1 192.168.1.0 255.255.255.0" and try again.

Or try adding something like this...

access-list outside_nat0 extended permit ip 192.168.1.0 255.255.255.0 192.168.1.0 255.255.255.0

nat (outside) 0 access-list outside_nat0

What device? ASA?

You will need the command "same-security-traffic permit intra-interface".

The command is already added. yes it is ASA.

i am also not able to ping ip between these clients.

just pasted below the respective configuration:

Check the stateful firewall in the vpn client. Uncheck Options -> Stateful Firewall (Always On)

Dear Acomiskey

It is already unchecked.... do you find any problem in config such as nat or access-list or inspect.. etc... are they configured correctly?

I had setup a lab with help of a L3 and ASA and used following configuration on ASA and i am able to run netmeeting . but not working with the client configuration which is mentioned in above thread.

In below LAB configuration netmeeting is working:
